STA-2

Ways to fix setup violations: Setup violation occurs because of high delay in the data path or due to negative skew. Below are the ways to fix setup violation: Gate sizing Buffering

Boolean Expressions-2

We hope you had a good understanding of Boolean Expressions which is available @ Boolean Expressions. In this blog, we will discuss on the simplification of boolean functions.

Logic Gates

We hope you had a good understanding of Number Systems which is available @ Number Systems. For building hardware, we need logic gates, combinational circuits and sequential circuits which takes input in the form of binary numbers. The main building blocks to design combinational and sequential circuits are logic gates which is explained below.

Boolean Expressions-1

We hope you had a good understanding of Logic Gates which is available @ Logic Gates. To reduce the logical complexities of any Boolean expression, a set of theorems have been developed which is explained below.

Number Systems

To start with VLSI skill development, we need to enhance our frontend skills. check the ASIC flow at ASICvsFPGA, which describes the frontend and backend flow for the full chip development. Frontend starts with specification gathering and architecture designing from the specifications gathered.

ASIC vs FPGA

Before starting the discussion on what is ASIC and what is FPGA, we will first learn about the basics that a VLSI enthusiast should know. Moore’s Law: Moore’s law is the observation that the number of transistors in a dense integrated circuit doubles about every two years.

Gate All Around FET

GAA is somehow similar to FinFETs except the conducting channel is surrounded by gate all around. Thus we get better gate controllability over the channel. The channel shape can be square or any other polygon shape.

Communication Protocols

UART stands for Universal Asynchronous Receiver-Transmitter. It is commonly used in the microcontroller to communicate with the peripheral. An 8-bit serial data coming from the peripheral device is converted into the parallel form using serial to parallel conversion and parallel data coming from the CPU is converted using parallel to serial conversion.

Bulk CMOS

CMOS technology uses both NMOS and PMOS transistors, The transistors are arranged in a structure formed by two complementary networks. Bulk CMOS is a chip built on a standard silicon wafer.

FinFET-2 (Multi-Gate FinFET)

In 1965, Gorden Moore in his paper predicted that how number of transistors in integrated circuit get double in every 18 month. Even though in 1990, a new type of substrate named SOI (Silicon-on-insulator) was introduced which improved the speed and power consumption, the first integrated circuit transistor was fabricated on “Bulk” silicon wafers.
